I just did with -F, got the message that Windows won't be able to boot from such a device, then get
Initializing device with zeroes:   0%  (now up to 3% as I type this on other computer.  I can wait, really need to go to bed.)

I wasn't planning to run MS-Windows, and don't know if there is anything else that could boot from NTFS.

Thanks for help!
